How important is S/N Ratio....?

Wavetrader,
I will love to upgrade the components n my components too, but have you ever wondered whether it might be detrimental to the flow of current when you use different solders to what was originally used on the circuit boards? Like the interactions between different alloys and the also the matter of whether the components will be mounted as stably as the ones originally supplied. Nowadays it's all surface mount. These are the main concerns that are preventing me to do such risky modifications. But if the amplifier is made by hand when purchased, I won't have any problems with that.

Wonderful.....I am no tech...but this amp has pull out CB's so the recapping was not that involved...the thing that was a challenge was fitting the low esr power caps. The solder issue you mention is better left to those that make their living...doing such things.

I will have a matching pre-amp with these ultra low noise caps vs a unit with some Nichicon gold installed.....if I get a quantum leap with the ULN type.....well it will be interesting.

Wavetrader - if you do this yourself be sure you know what you're doing. Installing low ESR caps with certain voltage regulators might cause oscillation.

Kijanki.....thanks for the warning.....I am lucky as I have one of the best techs in the country 10 minutes away.

Kijanki.....Let me clear that up....my tech Fred does all this work for me.....We have been friends since 1975. Fred has been doing this professionally for 40 years.
